TROUBLESHOOTING THROUGH A COMPUTER INTERFACE
In addition to the troubleshooting procedures outlined in Section 6.1, this section describes
interrogation of the LASAR
®
System operation through an IBM compatible laptop computer interface.
The LASAR
®
controller has the ability to digitally communicate with an IBM computer to display various
system conditions described below. The communication protocol is a RS-232 format operating at 9600
baud, 1 stop bit, 1 start bit and no parity.
6.2.1 Required Equipment
A.
T-232 Cable purchased through a LASAR
®
distributor interfaces through the RS-232
communication port of LASAR
®
controllers which are mounted to the controller housing with a
jam nut. Earlier controllers used a flange mount RS-232 connector with four screws securing the
connector to the controller housing. These earlier configurations require the use of a T-233
adapter with the T-232 cable.
B.
IBM compatible computer with Windows 3.1 or Windows 95 operating software.

should be routed away from the high voltage ignition harness, heat sources, control linkages or
any other critical aircraft system.
D.
Connect the T-232 cable to serial port COM1 of the computer.
